Java – How do I programmatically create a “.nomedia” file and store images in it?

For my app, the image

is stored in the phone’s internal memory, the image is visible in the gallery, but my client wants the image to be invisible in the gallery.

I

manually added the .nomedia file in the folder where the image was stored and it disappeared, but I took a new image again and it is visible in the gallery.

So how can I do this programmatically so that the images don’t show up in my gallery?

Here is my code.

public  void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode,data);

if(resultCode== Activity.RESULT_OK){

if(requestCode==REQUEST_CAMERA){
        Uri selectedImageUri = data.getData();
        if (null != selectedImageUri) {
             Get the path from the Uri

String path = getPathFromURI(selectedImageUri);
            File file = new File(path);
            Bitmap  bmp = CommonMethod.compressImage(file, getContext());
            Log.e(TAG, "onActivityResult --: "+ String.format("Size : %s", getReadableFileSize(file.length())));

mCustomerImage =  CommonMethod.bitmapToByteArray(bmp);
            imageTemplateStr = Base64.encodeToString(mCustomerImage, Base64.DEFAULT);
            Log.e(TAG, "image: "+ imageTemplateStr );
            imageCustomer.setImageBitmap(bmp);
        }

}else if(requestCode==SELECT_FILE){
        Uri selectedImageUri = data.getData();
        if (null != selectedImageUri) {
             Get the path from the Uri

String path = getPathFromURI(selectedImageUri);
            File file = new File(path);
            Bitmap  bmp = CommonMethod.compressImage(file, getContext());
            Log.e(TAG, "onActivityResult --: "+ String.format("Size : %s", getReadableFileSize(file.length())));

mCustomerImage =  CommonMethod.bitmapToByteArray(bmp);
            imageTemplateStr = Base64.encodeToString(mCustomerImage, Base64.DEFAULT);
            Log.e(TAG, "image: "+ imageTemplateStr );

imageCustomer.setImageBitmap(bmp);
        }

}

getPathFromUri method

public String getPathFromURI(Uri contentUri) {
    String res = null;
    String[] proj = {MediaStore.Images.Media.DATA};
    Cursor cursor = getActivity().getContentResolver().query(contentUri, proj, null, null, null);
    if (cursor.moveToFirst()) {
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        res = cursor.getString(column_index);
    }
    cursor.close();
    return res;
}

The compressImage() method.

public static Bitmap compressImage(File imgFile, Context context) {
    Bitmap compressedImgBitmap = new Compressor.Builder(context)
            .setMaxWidth(640)
            .setMaxHeight(480)
            .setCompressFormat(Bitmap.CompressFormat.PNG)
            .build()
            .compressToBitmap(imgFile);

return compressedImgBitmap;
}

Create a .nomedia file in storage to hide audio from the media player:

String filepath = Environment.getExternalStorageDirectory().getPath()+"/";

File file = new File(filepath+".nomedia");
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
